Easy to Use. Easy to use linear motion

Transcription

1 Easy to use linear motion Oriental Motor began by thinking from the user's point of view and a commitment to do whatever it takes to achieve what our users have requested. Oriental Motor then combined a number of advanced functions needed to obtain the high level of easy to use functionality that the EZ limo series includes today. Oriental Motor also worked to create a visual design that has never been seen in a factory automation environment. Based on the principles of making a product that was both easy to use and pleasing to look at, Oriental Motor is pleased to introduce the EZ limo series of linear motion products.

4 Useful Mechanical Ultimate User-Friendliness Offering a Wide Range of Utilities Up to 63 motion profiles can be set. The system provides a full range of utilities such as a teaching function, push function, area output function, selection of home detection modes and absolute feedback type. EZ limo also supports external pulse input, which means you can combine your existing controller with the EZ limo system. Pursuit of Mechanical Design Excellence Easy Combination of Multiple Axes If necessary, such as when palletizing the work, two axes can be combined using an optional dual axis mounting bracket. X-Y configuration (4 patterns) and X-Z configuration (4 patterns) can be implemented with ease. Features Pleasant, User-Friendly Operation An optional teaching pendant facilitates data setting and operation. The LCD monitor is easy to see, and the userfriendly controls ensure pleasant, trouble-free operation. You can set or edit various data on your personal computer using optional data editing software. T echnical Incorporating Proprietary Technologies from Oriental Motor, an Industry Leader New Closed-Loop Control The motor part houses a stepping motor with a position feedback device. When a condition presenting the possibility of a misstep is detected, the motor performs closed-loop control, thereby ensuring stable operation. Prevention of Hunting at Standstill Unlike conventional servomotors, the motor used in the EZ limo system is free from hunting. Low Vibration/Low Noise Even During Low- Speed Operation The new // series adopts a softwarebased smooth drive control to suppress vibration and noise even during low-speed operation, such as the return-to-home operation. Installation example: X-Y configuration Maintenance-Free for Long-Term Performance The drive mechanism uses THK's ball screw, while the guide mechanism adopts THK's LM Guide. The ball screw employs the QZTM lubrication system, while the LM Guide uses the Ball Retainer to retain the coupled rolling elements. These mechanisms give the system a considerable duration of maintenance-free performance. QZTM lubrication system (THK): High-density fiber net supplies appropriate amounts of oil, thereby preventing oil wastage and reducing environmental burden. Ball Retainer (THK): Individual balls are retained in a manner allowing smooth rotation while preventing contact with adjacent balls. Use of the Ball Retainer provides long-term, maintenance-free operating conditions and other benefits. * Ball Retainer and LM Guide are registered trademarks of THK Co., Ltd. Safety Installation example: X-Z configuration Thin, Compact Linear Slide The linear slide is only 31.5 mm high (EZS44). The ultra thin body helps save space at the installation site. Consideration for Safety and the Environment Environmentally Friendly The EZ limo system is constructed from carefully selected parts that exert a minimum burden on the environment. UL/CSA Standards The // series adopt a motor and controller certified by UL/CSA standards. CE Marking All EZ limo products bear the CE mark to indicate their conformance with the Low-Voltage and EMC directives. * See Conformance with EC Directives on p.13 & p. for details mm 5

5 Functions EZ limo : The Ultimate Combination of User-Friendliness, High Reliability and High Functionality Space-Saving Cable Outlet Orientation The cable outlet is facing downward, which contributes to the overall space savings by reducing the space needed to wire the cables. EZS Positioning Pinholes on the Table These holes help maintain positional repeatability when the work must be removed and then installed again for the purpose of maintenance, etc. EZS Stainless Sheet The mechanical parts of the linear slide are covered with a stainless sheet to keep out foreign particles. (The stainless sheet is also available as a spare part.) Linear slide height 31.5 mm EZS4 4 Drive method : THK s ball screw (The QZTM lubrication system provides a considerable duration of maintenance-free performance.) EZS Guide mechanism: THK's LM Guide (Ball Retainer provides long-term, maintenance-free operating conditions.) Easy Connection A connector provides a simple, onetouch connection to the controller. A power cable is also supplied for ease of connection. Easy Installation Both the mechanical parts and controller can be installed easily. Linear Slide: The linear slide body can be affixed directly from the top and bottom with screws. (EZS3 and 3 can be affixed only from the bottom.) Cylinder: The cylinder can be installed through the dedicated mounting holes, or via a flange connection using an optional mounting bracket. : The EZS/ series controllers can be installed with mounting screws or using a DIN rail. The // series controllers come with dedicated mounting brackets. * See p.62 to p.64 for details on the installation. EZS Mounting Reference Surface These surfaces help maintain positional repeatability when the linear slide must be removed and then installed again for the purpose of maintenance, etc. Real-Time Monitoring Information such as set data, current position and I/O status can be monitored in real time using an optional teaching pendant (sold separately). 6

6 EZS Function common to all series Function only available with the specified series Choice of Type or Type Feedback As long as power is supplied, the EZ limo system can proceed to the next operation without executing home detection, even given the occurrence of an overload or emergency stop error. Choose the incremental type if you want to execute home detection each time the power is turned on. The absolute type would be your choice if you want to start operation from the current position rather than the home position, when the power is turned on. Type The absolute type allows the movement of the table or rod to be followed and backed up, even when the power is cut off. EZS/ Series Two types of backup modes are available. Select the mode that best suits your application. Choice of Home Detection Methods You can choose the sensorless mode if you want to simplify the mechanical layout, or the sensor mode if you want to use sensors to detect home. Sensorless Home Detection Home detection is performed without the use of a home sensor. The home position can be adjusted. For the linear slides, the direction of home detection can also be changed. Home Detection Using Sensors Home detection is performed using home sensors. The sensors are available as options. (See p. 68 for the sensor set.) Operation Using External Pulse Input The EZ limo can be combined with your existing controller to serve as a driver. Programmable Functions Standard backup Provides a longer backup period Optional backup Provides better speed-follow-up capability Linear Slide/Cylinder Normal System Configuration [ Mode] // Series These models provide a long backup period of around days (approx. 36 hours). Teaching Function You can move the table to a desiredposition manually or by using the teaching pendant and store that position. Direct Teaching: Turn off the excitation of the motor and move the table or rod manually to the target position, then store that position in the motion profile. Linear Slide/Cylinder Customer s Mode Driver Mode Push Function Teaching Function Monitoring Function Pause Function *1 Area Output Function Type *2 Sensorless Home Detection Programmable When Combined with the Customer's [Driver Mode] Available Not available Notes: Certain functions cannot be used in the driver mode. Provide HOME, +LS and LS sensors (optional) and connect them to the controller you want to use. *1 Only for EZS and Series *2 Only for, and Series Direct teaching Remote Teaching: Use the keys on the teaching pendant to move the table or rod to the target position, then store that position in the motion profile. Push Function The rod can be held in a state of being pushed against the work or similar object, as with an air cylinder. The force used to push the work (push force) can be changed. The / series handles up to 63 push width/force profiles. Remote teaching 7

7 Functions Area Output Function A signal is output when the linear slide table or cylinder rod enters a set range during operation. Area Output Signal ON OFF Entering the area Within the set area Exiting the area Easy Data Editing You can set and edit various data on a personal computer (PC) using the optional data editing software. The software comes with a PC interface cable (five meters in length) used to connect the controller and PC. The software also provides various monitoring functions. See p.16 and p.65 for details. EZS Set Area Data Editing Software (Optional) Pause Function EZS The linear slide/cylinder can be stopped temporarily during operation, using an external signal. When the pause input signal (PAUSE) is turned ON, the linear slide/cylinder decelerates to a stop. When the START signal is turned ON again after the (PAUSE) signal is turned OFF, the linear slide/cylinder resumes operation from the position at which it had stopped. Data Editing Monitoring Multifunction (Stored-Data Type) Connection of Multiple Axes A maximum of 16 controllers can be connected, with data set separately for each of the controllers. There is no need to connect the teaching pendant to each of the controllers. Teaching Pendant A Maximum of 63 Motion Profiles Up to 63 motion profiles can be set by the controller. Two Motion Profile Setting Modes: Mode and Mode You can set motion profiles in the absolute mode or incremental mode, depending on your preferred movement of the equipment. Mode (-Position Specification) : Each position is set as the absolute position with respect to the reference point. This is suitable when you want to move the work directly from an arbitrary position to the specified position. Reference Point Target Position C (5 mm) 5 mm Target Position A ( mm) mm Target Position B (18 mm) 18 mm 8

8 EZS Function common to all series Function only available with the specified series Mode (Relative-Position Specification) : Each position is relative, being set as an amount of travel from the current position or another target position for the work. This is suitable in a regular feed or other operation where the same pattern is used repeatedly. Target Position C (5 mm) Reference Point Target Position A ( mm) Target Position B (18 mm) mm 8 mm 23 mm When a line-driver output is used, connect a terminal resistor between the line-receiver inputs. When an open-collector output is used, keep the cable length to 2 m or shorter. With an open-collector output, the output waveform changes depending on the load condition. Check the operation of the connected equipment. Two Data Execution Modes: Selective Positioning and Sequential Positioning Selective positioning mode: The set data can be selected at random. Sequential positioning mode: Positioning operations are performed sequentially from the desired data. Functions Simple Unit Setting Travel amount, operating speed and acceleration/deceleration can be set directly as mm, mm/s and m/s 2 values, respectively. There is no need for pulse conversion, which allows for more efficient operation of a linear-motion product. Continuous Operation via External Signal Continuous operation can be performed while an external signal (FWD, RVS) is ON. This mode is ideal when you want to move the work via external control without using the teaching pendant. Output of Current Position and Error Code The current position, error code and certain other data can be output to an external device. Programmable Request (Command) I/O Output the present position or error code, etc. Table/Rod Position Monitor A counter or similar device can be connected to monitor the position of the linear slide table or cylinder rod using phase-a/b pulse signal outputs.

The second operation starts. The 62nd operation starts. The 63rd operation starts. The 64th operation starts. Separate Acceleration and Deceleration Settings Acceleration and deceleration can be set separately for each motion profile. This feature is useful in a quick acceleration/slow deceleration operation where the motor rises quickly and then decelerates slowly to a stop. [The opposite pattern (slow acceleration/quick decelerationis also supported.] EZS/ Series: Each motion profile has its own acceleration and deceleration settings. // Series: One common acceleration and deceleration setting for all motion profiles Speed Quick Acceleration Slow Deceleration BSG1 Time (When the slider table or cylinder rod is moving to the counter-motor side) Notes: The phase difference between A and B is 9 electrical. The pulse output accuracy is within.1 mm. Pulse output is subject to a maximum delay of 1 ms with respect to the actual movement of the linear slide table or cylinder rod. Use this function to check the stop position. Pulse output is possible at up to the maximum operating speed of each series. When counting the number of pulses, use a frequency counter that can count frequencies of at least twice the frequency level of the applicable maximum speed. Maximum speed and frequency Series : 8 mm/s (8 khz) Series : 6 mm/s (6 khz) Series : mm/s (6 khz) 9 Linked Operation Up to 63 motion profiles (for EZS/ Series) or 4 motion profiles (for // Series) can be linked, thereby allowing the motor to change speeds without stopping. Note: The motion profiles must create a motion in the same direction in order to be linked. Speed Operating Speed 2 Operating Speed 1 Operating Speed 3 Time
